I think it's dangerous to have lots of time on your hands as a writer. Time to pursue every little alleyway, to follow every single whim. I feel I've done my best writing when I'm stretched for time, when you're most pressured.

I always had the urge to write. Not in the sense of wanting to be a writer, but just writing things down, getting words on a page. Graphomania, it's called. I've always had a definite love of stationary products - I used to spend all my pocket-money on pens and notepads. I still do, in a way.

For a while I used to listen to those whispers about babies costing you books, and Cyril Connolly's loathsome quote that "There is no more somber enemy of good art than the pram in the hall." But it's rubbish. Absolute rubbish. A huge amount of your work is done when you're not at your desk. Knotty problems that you need your unconscious to solve. So it can be helpful to walk away and focus on other things and it can be helpful to be a bit harassed in your daily life, to be hungry for time to write.

The Chilean novelist Isabel Allende says there's no such thing as writer's block, you just need to live a bit more. I try to bear that in mind.

I have no control, of course, over how I'm marketed. It's a sad thing, though, that so many people perceive literature to be gendered. The idea that some subjects are male and some are female is just preposterous to me. It's reductive and nonsensical, to separate writers and subjects and plots along gender lines. It's meaningless.

While I was writing the book, one of my children was diagnosed with dyslexia. Dyslexia is a very tiny word for a wide-ranging neurological condition that affects different people in different ways. But I was reading an awful lot about it, to try and find ways of helping my child. I think a lot of fiction comes from this desire to confront unanswerable questions, and it's heartbreaking to see your child, a bright child, struggling so much with something that others are finding so easy. It's such an assault to the child's self-esteem and, as a mother, it's hard to watch.

Gretta sits herself down at the table. Robert has arranged everything she needs: a plate, a knife, a bowl with a spoon, a pat of butter, a jar of jam. It is in such small acts of kindness that people know they are loved.
